Description

Technical Field

[0001] This utility model relates to the field of track technology, specifically to a circumferential stop device for the horizontal rail of a ring cooler. Background Technology

[0002] The ring cooler equipment used in the sintering branch of the ironmaking plant has a trolley that runs on inner and outer ring tracks. The curved track uses 50kg / m rails. When the track is fixed circumferentially on the track beam, welded track pressure plates and bolt-fastened pressure plates are alternately arranged on the lower rail surface for positioning and fastening. When the track is fixed radially, welded blocks are alternately arranged on both sides of the track. There are two types of blocks: the block is placed on the web plate and on the side of the lower rail surface.

[0003] In actual use, the track moves circumferentially along the direction of the trolley body, causing the gap at the front track joint to accumulate to 5-10cm. The rear track joint is squeezed and deformed, breaking the radial positioning block and cutting off the connecting plate bolts at the track joint, resulting in a deterioration of the track's operating condition.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figure 1-5As shown, a circumferential stop device for a horizontal rail of an annular cooler includes a bottom beam 1 and a pad 2, which is disposed on the top of the bottom beam 1. A rail 3 is fixedly connected to the top of the pad 2. The pad 2 is disposed between the rail 3 and the bottom beam 1 to adjust the elevation of the rail 3. A through groove 4 is opened inside the rail 3 at the connection point of the rail 3. Connecting blocks 9 are fixedly connected to both sides of the rail 3 to connect and fix the rail 3 together. A thrust assembly 5 is disposed inside the through groove 4. A thrust plate 6 is also disposed inside the through groove 4 to limit the circumferential movement of the rail 3. The thrust assembly 5 and the thrust plate 6 effectively prevent the rail 3 from moving in the circumferential direction.

[0024] It should be noted that by cutting a through groove 4 of a certain size at the bottom of the track 3, the thrust assembly 5 and the thrust plate 6 are installed inside the through groove 4 to reinforce the track 3 and prevent the track 3 from moving in the circumferential direction.

[0025] The pad 2 includes an iron pad 201, a rubber pad 202, and a slot 203. The iron pad 201 is fixedly connected to the top of the bottom beam 1. The rubber pad 202 is detachably installed on the top of the iron pad 201. The slot 203 is formed inside the rubber pad 202. The iron pad 201 is welded to the top of the bottom beam 1. The rubber pad 202 is snapped between the track 3 and the iron pad 201. The high elasticity of the rubber pad 202 can effectively absorb the impact and vibration during train operation and reduce the noise transmitted by the track structure. The slot 203 has a honeycomb or corrugated surface design, which increases the elastic deformation space and disperses stress.

[0026] The thrust assembly 5 includes a connecting plate 501 inserted into the through groove 4. A thin pad 502 is provided on the top of the connecting plate 501. A mounting bolt 503 is inserted into the inside of the connecting plate 501, and the mounting bolt 503 passes through the connecting plate 501, the thin pad 502, the iron pad 201, and the top of the bottom beam 1. The connecting plate 501 passes through the through groove 4, and its bottom is supported by the thin pad 502. High-strength mounting bolts 503 are used to pass through the bottom beam 1, the connecting plate 501, the thin pad 502, and the iron pad 201 to secure it. Then, the connecting plate 501 is welded to the iron pad 201, and the iron pad 201 is welded to the bottom beam 1. The weld is required to be full, and the height shall not be less than 2 / 3 of the plate thickness.

[0027] The thrust plate 6 is T-shaped, with one end embedded inside the through groove 4 and the other end welded to the top of the iron pad 201. The thrust plate 6 has reinforcing ribs inside. The direction of the reinforcing ribs is to prevent the track 3 from moving. The thrust plate 6 is embedded in the through groove 4 on the lower rail surface of the track 3 as an auxiliary reinforcement measure for the thrust plate at the track joint.

[0028] The connecting block 9 has a groove 10 inside and is fixedly connected to the outside of the track 3 by a fixing bolt 11. The groove 10 makes the connecting block 9 C-shaped, and the two ends are engaged with the track 3, which improves the connection strength between the connecting block 9 and the track 3.

[0029] A pressure plate 7 is provided on the outer side of the track 3. The pressure plate 7 is welded or fixed to the top of the pad 2. The pressure plate 7 is used to press the track 3 tight.

[0030] A radial thrust plate 8 is welded at the connection between track 3 and pad 2. The radial thrust plate 8 is an important functional component of the track system, mainly used to limit the displacement of the track in the lateral (radial) and longitudinal directions, ensure the stability of the track geometry, and distribute the dynamic load generated during train operation.

[0031] Working principle: By cutting a through groove 4 of a certain size at the bottom of the track 3, the connecting plate 501 is inserted through the through groove 4 and its bottom is supported by a thin pad 502. High-strength mounting bolts 503 are used to pass through the track bottom beam 1, the connecting plate 501, the thin pad 502 and the iron pad 201 to secure it. Then the connecting plate 501 is welded to the iron pad 201 and the iron pad 201 is welded to the track bottom beam 1. The weld is required to be full and the height should not be less than 2 / 3 of the plate thickness. This reinforcement treatment of the track 3 effectively solves the problem of circumferential movement of the track 3.
